Nonlinear Analysis Of High-Rise Steel-Concrete Composite Structure

Currently, the composite structure generally refers to the steel (including steel rolling or welding forming, steel) and concrete composition of the structure, referred to steel-concrete composite structure, composite structure by the steel and concrete structure evolved, so has the steel composite structure the corresponding structure and concrete structure features. At the same time the structure is a combination of two materials together to form the force components relative to the individual components of two materials, can better play the two properties of the materials, but also has more advantages.With the continuous development of high-rise buildings, the traditional structure of high-rise buildings in a multi-use more and more restricted, in order to adapt to the development of modern architecture, the use of composite structure to optimize the structure of traditional design with good results.This paper builds a model of normal steel, beams and plates used in conventional reinforced concrete, in order to study the advantages of composite structure, the paper changed the model a second model will be the model into a reinforced concrete beam in the processing of concrete section forms the word combination of steel, the model will model the three reinforced concrete slab of a change in the pressure-based composite slabs, the model four-combined in two ways to change their ways to make further changes to the structure using time history analysis to calculate analyzed the role of the four models under the floor of the earthquake the maximum displacement, and maximum column axial force and maximum shear beam, through a series of comparative analysis to identify the advantages of composite structures. Also pointed out that the composite structure compared to the original structure can produce a range of negative effects. This article cited a specific example to illustrate the composite slab construction cost savings. For many high-rise building structure, the composite structure of the application of good development prospects, while their research also has great practical value.
